This has never happened before.

I skipped my period last week but this happens often. I know some peoples’ breasts swell on their period or during pms, but I have had my period for nearly 7 years and this has never happened to me before. My back hurts because of it.

They are both swollen but one much more than the other. The one that’s more swollen has stabbing pain.

Please explain if this is normal or what to do if it’s not.

(My nipples are a bit cold in this but they are also flatter and more puffy than normal)
